0.5.1

This is a bug fix release which addresses issue 157. This issue only affects the shasta-OldLinux-0.5.0 executable and the Ubuntu 16.04 build. If you are using the shasta-Linux-0.5.0 executable or one of the macOS executables you are not affected by this issue and you don't need to upgrade to this release.

This release is compatible with Shasta release 0.5.0. However, it is not compatible with previous Shasta releases. There were incompatible changes in some command line option names, the binary formats used, and the Python API. You cannot use release 0.5.0 or 0.5.1 for post-processing of an assembly done using a previous release.
